# Getting Started

## <mark style="color:blue;">Start by using our API</mark>

Using DeepDAO's API for creating a segment of the DAO Participants population is easy.&#x20;

### **Step 1**

Get your API key. Head to [DeepDAO's Plans](https://deepdao.io/plans) page, and purchase a key for the Marketing plan.&#x20;

### **Step 2**

Read our [API documentation](/deepdao-products/governance-list-the-top-daoists/api-documentation.md) and start creating your marketing lists right there.&#x20;

## <mark style="color:blue;">Custom lists</mark>

Our API allows significant flexibility in selecting your segment of the DAO voters population across several criteria. However, you may want a segment that is not available through the API, or a different format for delivering your data.&#x20;

For custom lists please write to us at <info@deepdao.io>.&#x20;
